Full analysis
The 2026 midterm prediction markets are massive, with total volume exceeding 4 million. The key contracts: CONTROLH-2026-D (Democrats hold House) at 84¢ with 37k volume; CONTROLS-2026-R (Republicans win Senate) at 52¢ with 18k volume; and the dead‑heat Texas Senate race (SENATETX-26-R at 50¢, SENATETX-26-D at 48¢). The House popular vote margin (KXHOUSEPOPVOTEMARGIN) shows Republican margin at 9¢. The balance of power combo contracts (KXBALANCEPOWERCOMBO) are also heavily traded – a Republican House + Democratic Senate is at 1¢, Democratic House + Republican Senate at 38¢, and full Democratic control at 46¢. These combos reflect the market’s view of a split government. For traders, the most liquid contracts are the individual House races like TX-15 (44¢, 250k volume) and the Florida Senate race (SENATEFLS-26-R at 91¢). Any new scandal, endorsements, or economic data will cause rapid repricing. The Brazilian presidential primary (KXBRPRES-26-FBOL at 41¢, KXBRPRES-26-LULA at 55¢) adds international flavor – a Bolsonaro comeback could impact emerging market risk.
